Octal comes up almost exclusively in Unix file permissions, which makes it dead weight for the conversions that actually happen constantly in everyday programming, a hex color value, a memory address, a binary flag, all of which only ever need binary, hexadecimal, and decimal, never a fourth base that rarely applies to the task at hand. This tool converts between binary, hexadecimal, and decimal instantly, focused specifically on the three bases that come up in daily coding work rather than including a fourth one that mostly just adds clutter.

Useful for converting a hex color value into decimal RGB components without an unnecessary octal field in the way, checking a binary flag's decimal equivalent during a quick debugging session, or converting a memory address between hex and decimal for the bases that actually matter day to day.

Quick answers for BIN HEX DEC Converter

Do I need to convert one pair of bases at a time?
No. Pick a single input base and enter a number, and the result shows all three: binary, decimal, and hexadecimal, at once, rather than making you choose a separate output base each time.
What does the Next Base button do?
It cycles the input base through binary, decimal, and hexadecimal in sequence and clears the current input, a quick way to switch what you're typing without opening a dropdown.
Can I feed one of the results back in as new input?
Yes. Each conversion result has a "Use as input" link that loads that value, in its matching base, back into the input field so you can continue converting from there.
